Arizona Public Service last week filed a 15-year Integrated Resource Plan that predicts a 60% growth in resource requirements and outlines a broad range of new resources to meet the need.
While renewable energy and battery storage will both help, APS told the Arizona Corporation Commission that it will lean heavily on natural gas to meet growing demand. Gas-fired energy will grow from 26% of the utility’s supply mix this year to 33% by 2032.
